The Story
Plant Bio
Camellia sasanqua is an evergreen shrub with smaller leaves and a more open habit than C. japonica. They are valued for their profuse fall to early winter blooms and greater sun tolerance.
Developed by Dr. Michael Dirr, 'Susy Dirr' is valued for its improved cold hardiness (to Zone 6b) and abundant, semi-double, lavender-pink flowers. It has a dense, vigorous growth habit.

Care Guide
Do
- Provide consistent moisture, especially during the first year.
- Fertilize in spring with a formula for acid-loving plants.
- Prune after flowering in winter to maintain shape and density.
- In colder zones, provide winter protection with mulch and a sheltered site.
Don't
- Do not plant too deep; this is a primary cause of failure.
- Avoid letting the soil become completely bone-dry.
- Don't fertilize late in the season, as this can push tender new growth.
- Never pile mulch up against the main stem of the plant.
